Item 1.01 Entry Into A Material Definitive Agreement. Third Amendment to the Merger Agreement On May 6, 2026, BOXABL Inc. (“ BOXABL ”) entered into a Third Amendment (the “ Third Amendment ”) to that certain Agreement and Plan of Merger, dated as of August 4, 2025, as amended by the First Amendment to the Agreement and Plan of Merger dated November 3, 2025, as amended by the Second Amendment dated April 6, 2026 (collectively, the “ Merger Agreement ”), by and among BOXABL, FG Merger II Corp. (“ FGMC ”), and FG Merger Sub II Inc. (“ Merger Sub ” and together with BOXABL and FGMC, the “ Parties ”). Capitalized terms used herein but not defined herein have the meanings ascribed thereto in the Merger Agreement. Pursuant to the Amendment, the Parties to the Merger Agreement agreed: (A) to delete and replace in its entirety the form of Company Lock-Up Agreement attached to the Merger Agreement as Exhibit A-1 with a revised form of Company Lock-Up Agreement. The revised Company Lock-Up Agreement provides for a lock-up period commencing on the Closing Date under which (i) 50% of the Lock-up Shares shall be released on the date that is six (6) months from the Closing Date, provided the price per share of the Surviving Pubco Common Shares meets or exceeds $12.00 per share for any twenty (20) trading days within any thirty (30) trading day period, and (ii) any remaining Lock-up Shares shall be released on the date that is thirteen (13) months from the Closing Date, irrespective of share price. The lock-up period terminates early if the trading price per share of the Surviving Pubco Common Shares meets or exceeds $20.00 per share, including during intra-day trading; and (B) to delete and replace in its entirety the form of Sponsor Lock-Up Agreement attached to the Merger Agreement as Exhibit A-2 with a revised form of Sponsor Lock-Up Agreement. The revised Sponsor Lock-Up Agreement provides for a lock-up period under which (i) 50% of the Lock-up Shares are released on the earlier of twelve (12) months following the Closing Date or the date on which the closing price of the Surviving Pubco’s Common Shares equals or exceeds $12.00 per share for any twenty (20) trading days within any thirty (30) trading day period, and (ii) the remaining 50% of the Lock-up Shares are released twelve (12) months following the Closing Date. Early release of all remaining Lock-up Shares occurs if the Acquiror Common Stock trades at or above $20.00 per share, including during intra-day trading. The Sponsor Lock-Up Agreement amends and restates the Insider Letter (dated January 28, 2025) in its entirety. The foregoing summary of the Amendment does not purport to be complete and is qualified in its entirety by reference to the Amendment, a copy of which is filed as Exhibit 2.1 and is incorporated by reference herein.
